Application filed March 2,1905. Renewed June 6,1906. Serial No. 320,452.

To aZZ whom, it may concern:

the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which we declare the following to be a full, clear, and exact description.

This invention relates to an improvement n looking. devices for cash registers, it belng among the objects thereof to combine in one common device various locking features which hitherto have been accomplished by separate devices, thus dispensing with the necessity of multiplication of numerous small parts of the machine.

Stated in general terms, the invention relates to a device for locking the keys of a cash-register from movement while the cashdrawer remains open and unlocking the same when the drawer remains closed, this drawer operative locking means, however, being disabled by a manipulative device which upon adjustment permits the operation of the keys regardless of the position of the drawer, and both of these devices being supplemented by an ordinary lock, the key of which is retained by the proprietor, which lock when operated acts upon the same looking device permanently to lock the keys from movement regardless of the position of said manipulative means or of the position of the cash-drawer.

TVith these and incidental objects in view the invention consists in certain novel fea tures of construction and combinations of parts, the essential elements of which are set the general functions of the same is necessary. The keys 10 are pivoted upon a transverse shaft 11, and extending transversely across all of the keys is a common member 12, pivoted at 13 to the main frame of the machine, so as to be moved upward by the depression of any one of the keys. In this particular case the common member 12 is the ordinary form of keycoupler. This key-coupler has formed upon its side two locking projections 14 and 15, and between these two projections swings a locking-arm 16, pivoted to the main frame at 17 and formed with two locking-notches 18 and 19, arranged to engage, respectively, the two locking projections 14 and 15.

The lower portion of the arm 16 is formed with a rearwardly-extending arm 20, which carries a pin 21, projecting into a slot in the upper end of a bell-crank lever 22. The lower end of this lever projects downward into the casing in the path of the rear end of the cash-drawer 23. The upper end of the lever 22 is normally drawn rearward by means of a spring 24, so that when the cash drawer is open the lever assumes the position shown in Fig. 1, in which the lower end of the lever is thrown forward and the upper end is thrown rearward, thereby carrying the locking-notch 19 over the locking proj ection 15, and thereby preventing the movement of the common member, and consequently locking the keys from movement. When the cash-draweris closed, the rear end of the same strikes the lower end of the lever 22 and carries the upper end thereof forward sufficiently to swing the notch 19 out of engagement with the projection 15, but not far enough to cause the notch 18 to engage the projection 14, so that the arm 16 occupies the position intermediate the two locking projections, and the common member is therefore unlocked, so that any of the keys may be operated this general result of locking the key-coupler when the cashdrawer is open and then looking the same when the cash-drawer is closed being of course well known in the art at the present time. In case it is desired to disable this drawer-operative locking means a manipulative device is provided, consisting of a bar 30, which may, if desired, be situated within the ordinary lid of the cash-register or may extend through the casing to be at all times accessible to the operator. The forward end of this bar is formed with a slot having two spaced recesses 31 and 32, into which projects IoWhich projects a pin 35, formed on the upper end of the locking-bar 16. In the position shown in Fig. 1 the pin 33 occupies the recess 32 of the bar 30, so that the bar is retracted enough to permit the operation of the draweroperative locking means, as previously de scribed. hen, however, the bar is adjusted to the position shown in Fig. 2, in which the pin 33 engages the recess 31, the rearward end of the bar is moved to such an extent that it engages the pin 35 and moves thelOcking-bar 16 into an intermediate position of rest between the two locking projections, thereby carrying the lower end of the lever 22 out of the range of operation by the cash-drawer, and thus permitting the continued operation of the keys irrespective of the position of said drawer. Since, however, it is often desirable permanently to lock the machine against operation, an ordinary form of lock is provided, the key of which may be retained by the operator or the cashier and the bolt 41 of which lock (see Fig. 3) is arranged when the lock is operated to engage a lateral projection 42, extending from the upper end of the locking-bar 16. The extent of movement of the lockingbolt 41 is sufficient to carry the lower end of the lockingarm 16 to its extreme forward position, whereby the lockingnotch 18 may engage the locking projection 14, as shown in Fig. 3, the length of the slot 34 in the bar 30 being suficient to permit this extent of movement of the arm 16 independently of the bar 30, even though the bar 30 were adjusted to its extreme forward position. It is thus seen that the proprietor may, if he desires, permanently lock the machine from operation by means of his private key and the operation of the bolt 41 upon the locking-arm 16 in the manner described. It is apparent that this locking-arm 16, with its two extreme positions, performs these locking features as controlled by the drawer and the private look and in its intermediate 'position between said extreme positions permits the continued operation of the machine independently of the position of the drawer, thus aifording an economy of parts and a simplicity of construction which has not been present hitherto in machines of this character.

While the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not desired to confine the invention to the one form of embodiment here disclosed, for it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a cash-register, the combination with a series of keys, and a member movable with said keys, of locking projections formed on said member; a locking device formed with provisions for engaging said locking projections; and means for adjusting said locking device to position the same to engage any one of said locking projections or to occupy an intermediate inoperative position between the projections.

2. In a cash-register, the combination with a series of keys, and a member movable therewith, said member being formed with two locking projections, of a locking-arm arranged to swing between said projections and formed with provisions for engaging the same; a cash-drawer; means controlled by the drawer for causing said arm to engage one of said devices; and a manipulative device for movingsaid arm to engage the other projection.

3. In a cash-register, the combination with a series of keys, and a member movable therewith, said member being formed with two locking projections, of a locking-arm arranged to swing between said projections and formed with provisions for engaging the same; a cash drawer; means controlled by the drawer for causing said arm to engage one of said devices; a manipulative device for moving said arm to engage the other projection; and a second manipulative device for adjusting said arm to an intermediate position between said projections whereby to disable the locking effect of said arm.

4. In a cash-register, the combination with a series of keys, and a common member movable thereby, said member being formed with two locking projections, of a locking-arm swinging between said two projections and formed with provisions for engaging the same; a cash-drawer; means operated by the cashdrawer for moving said arm to engage one of said projections when said drawer is open; a manipulative device for moving said arm to occupy an intermediate position between said two locking projections whereby to disable the drawer-operative locking means; and means under lock and key for moving said arm to engage said other projection to permanently lock said member.

5. In a cash-register, the combination with a series of keys, and a common member movable therewith and having formed thereon two locking projections, of a locking-arm ar ranged to swing between said projections and formed with locking-notches for engaging the same; a cash-drawer; a lever connected with said locking-arm and normally drawing the same into position to engage one of said looking projections whereby to lock the common member and the keys from movement, said lever being positioned to be engaged by said drawer when closed, whereby to move said arm out of engagement with said locking projection; a manipulative device having slotand-pin connections with said locking-arm and having two adjustable positions one of which permits the normal operation of said drawer operative locking means and the other of which disables said drawer-operative locking means by moving said locking-arm to occupy a position intermediate said two lockmg projections; and a special lock including a locking-bolt, which bolt engages said locking-arm and moves the same to engage the second locking projection whereby to permanently lock said common member and the keys from operation independently of the adjustment of said manipulative device or of the position of said drawer.

6. In a cash-register, the combination with a series of keys, an operating member and a cash-drawer; of a single locking member for cooperating with said operating member; means connected with said drawer for controlling said locking member; a manipulative device for disabling said drawer-controlled means so that the effectiveness of the locking member is independent of the drawer; and a second manipulative device for permanently controlling said locking member independently of'either said drawer-controlled means or of said first-mentioned manipulative device.

7. In a cash-register, the combination with a series of keys, an operating member and a cash-drawer; of a single locking member for cooperating with said operating member; means controlled by said cash-drawer for operating said locking member to lock the operating member when the drawer is open; a manipulative device for preventing the looking of the operating member by the locking member when the drawer is open; and a sec ond manipulative device for permanently acting on said locking member and causing the same to lock the operating member inde pendently of either said cash-drawer or of said first-mentioned manipulative device.

In testimony whereof we aflix our signatures in the presence of two witnesses.
